Universities give external IPs to internal hosts with all ports accessible? That seems unlikely, if only due to IPv4 address space crunches.

- tomjen3 15y agoMIT has, what, 1/5th of the global IPs? They have no crunch.
- ixnu 15y agoThis unlikely scenario is in fact true on my campus where I'm an admin. In fact, we are dissuaded from even NAT'ing because it complicates central auditing and internal charge backs. Every single wired host (including printers) has Class B public IP address.
- protomyth 15y agoI know of at least one college management system that "requires" this.
- jff 15y agoThat's how it was at my school. It was actually very nice, because you could run your own servers from your dorm room or the lab with ease. The only thing they blocked were mail servers, and I think you could get an exemption. There were basically no limits set on our network, and they even left the Direct Connect hubs alone unless somebody reported them... primarily because when the hubs went down, our outbound link would be completely saturated by bittorrent traffic.
- mikeash 15y agoA lot of universities got in on the internet early and ended up with huge blocks of IP addresses. Stanford University had the entire 36.0.0.0/8. They gave it back, but others have not been so charitable.
